Ground fault circuit interrupter (GFCI)
The ground fault interrupter/residual current detector installed in this system is a Non class A GFCI,
intended for equipment protection.
Familiar yourself with its operation and required setting.
At installation and commissioning stage use a calibrated milliamp meter to read and record the
heating systems natural leakage.
Set the GFI/RCD to no more than 30 milliamps higher than that reading.
This step might have to be repeated a few times, to avoid nuisance tripping.
The GFCI should be tested monthly. Please refer to the calibration and testing instructions in
appendix 1 of this manual.
